DESCRIPTION:

The MSK 4891 is one of a family of plastic encapsulated modules (PEM) developed specifically for use in military,

aerospace and other severe environment applications. The SCR/DIODE configuration and 600 volt/300 amp rating make it

ideal for use in high current motor drive and inverter brake applications. The Aluminum Silicon Carbide (AlSiC) baseplate

offers superior flatness and light weight; far better than the copper or copper alloys found in most high power plastic

modules. The high thermal conductivity materials used to construct the MSK 4891 allow high power outputs at elevated

baseplate temperatures. Our proprietary coating, SEES™ - Severe Environment Encapsulation System - protects the internal

circuitry of MSK PEM's from moisture and contamination, allowing them to pass the rugged environmental screening

requirements of military and aerospace applications. MSK PEM's are also available with industry standard silicone gel

coatings for a lower cost option.
